The writers, Paul Epworth and Adele, described "Rolling in the Deep" as a "dark blues-y gospel disco tune." As we started arranging this cover, the song came alive when we found a destined matchup in the melody from Gustav Holst's classical piece "Jupiter"—a deep melody that rang out when layered on top of everything we were creating for this arrangement. To make a long studio-story short, it all came together after that. ALL sounds were created by acoustic & electric cellos (5 different cellos) and piano. By the time we were finished we had used 60 tracks.
In this arrangement we borrowed a melody from Gustav Holst's "Jupiter" Suite from "The Planets" -- op. 32 -- be sure to listen to his original composition -- it's amazing! The melody we used comes in about half-way through the piece.
